FLUSH-OUT VALVE.v

Specification ofLetters Patent.

Patented Nov. 18, 1913,

f applica/ion area umn 22, 1era.' serial No. 756,125.

To all lwhom it ma/ t/ concern:

Be it known that we, Aeos'r-INo'Tosoo and PAUL SALINA, citizens of the United States, residing at San Francisco, in the count of San Francisco and State of California, ave invented new and useful Improvements in Flush-Out Valves, of which the following isa s cification.- v

This invention relates to a flushing ap- M, paratus forwater-closets and the like, and particularly pertains to a flush-out valve therefor.

It is the object of this invention to' provide a flushing apparatus for water-closets .15, which is adapted to deliver the same yamount of water upon every occasion andA which operates to discharge a large flush at first to insure flushing the water-closet bowl, and a-small flush at the last so as to properly lill the bowl and seal the trap;

Another object is to rovide a flush-out valve which is simple and cheap in construe tion, efficient in operation, durable, and which may be easily and quickly removed g5 and replaced at small cost when worn or damaged. l

A further object is to provide a iushout device of the type employing a hollow rubber ball as a valve, and to rovide means a@ for guidingand directing tie ball to its seat after being unseat/ed, so that it will not forcibly strike or impact the seat but will move gently to its seat'ed position, thereby preventin the ball from becoming distorted and miss apen and consequently increasing its durability and efciency.

Other objectswill appear hereinafter.

The invention primarily resides in a flush pipe', having` a valve seat formed theron,

ace on the valve seat b the liquid in the ushing tank to which: t e flush means for projecting the ba a cage in which the ball travels and formed a5 to retain the ball out of its seated osition until the liquid inthe tank falls elow a predetermined level, and so arranged as to direct the ball back to its seat on the surface of the liquid in a horizontal direction.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying, drawings, `inI which- Figure l. isqa side elevation of. the invention, shownas applied toy a ,flushing pipe is attached, l out of its seat,`

tank, a ortion of the latter being broken away. ig. 2 is' a plan view. Fi 3 is ai vdetail elevation on the line 1f-a o Fig. l. Fig. 4 is a vertical section in partial elevation of a modified form of Athe invention as applied to a flushing tank with portions broken away.

In the drawings, A represents a tanli of any suitable constructiom, and B is a flush pipe connected to the bottom thereof, the upper end of which connects with an overflow pipe 2 extending upward-ly in the tank A andterminatin at a suitable point therein. Formed on t e flush pipe B, adjacent thebottom of the tank A is a valve seat 3.

Y This seat is circular in p an and is preferably arranged at an angles of approxmatel 4'5", as shown-in Figs. l and Il. The oveii flow pipe 2 extends vertically adjacent the upper edge-of the valve seat 3 and mounted on the overfiow pipe 2 is a` sleeve 4, which is secured to the pipe 3 by meansof set screws 5` or in any suitable manner. Mounted on the sleeve 4 is awire cage,which is shown in. Figs. l and 2 as comprising a series of horizontally extending wires 6 andl 6"spaced a suitable distance apart and adapted to inclose'a floating ball 7 preferabl 4formed of rubber or similar material, wliich ball forms a valve and is adapted to rest on the valve seat 3; the upper horizontal wirey 6 of thexcalge being arranged to normally retain the all valve 7 in close proximity to the valve seat 3 in a submerged position vwhen the tank A is filled with water or other liquid. The wire (j is bent upwardly at its outer end, as indicated at 6, to form a pocket adapted to receive the ball 7 and hold it against movement when the bally is projected thereinto, as will presently be de'- scribed. Thehorizontal wires 6 serve as guides to conlinethe ball 7 against lateral movement; the wires 6-6 co-acting to con fine the travel of the ball 7 to a horizontal direction.

In the form of the invention shown inu Figs. l, 2 and 3, the means for projecting the ball 7 out of its seat is shown as consistin of a downwardly extending arm 8, w ich is pivotedat 9 at its upper end toa sleeve 10, secured to the upper end of the overflow pipe 2 by means of a thumb screw l1, or in any other suitable manner. The

lower end of the arm 8 is forked to form a pair of spaced parallel portions or prongs 3, which pass astride o the wire 6 and eX,-

an equal amount of Water on every occasion, and as before stated, an after-wash effected by `the breaking of the column of water entering the flush pipe B immediately before the seating of the valve 7.

The principal feature of this invention resides in directing the ball 7 back to its seated position in a horizontal direction and in such manner that it will not strike the valve seat 3 with a forcible impact, thus lengthening the life of the ball 7 and increasing its eliciency, as it has been found where floating rubber balls 7 have been ernployed as valves, that when they become distorted and misshapen by impact with the valve seatl they be'come ineHective and necesitate frequent renewal.

Having Ithus described our invention, what we claim and desire to secure by Letters Patent is:

In a flushing apparatus of the character described, a tank, a vertical overiiow pipe located therein and a iushing discharge pipe with which said overliow pipe connects at the lower end, a valve seat connecting with the discharge pipe out of line with the overflow and at an angle of approximately fortyive degrees, a buoyant spherical valve, an open wire cage by which the valve is normally directed upon the seat, an arm contacting with the ball, and lever connections by which the arm is actuated to throw the ball diagonally out of line with the seat, the upper member of said cage forming concave rests to retain the ball until the water level is depressed sufliciently to allow the ball to disengage and return to its seat.

, In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
